According to Don Harper, Professor Emeritus at TAMUG (and Dale Hubbard's former invertebrate zoology prof), this "must be a enteropneust hemichordate. I don't know of anything else that has a collar like that." Also referred to by the common name "acorn worm."
ReplyDeleteThanks Dale (and Professor Harper)! You have educated us all.
ReplyDeleteA quick search reveals that Enteropneusta is the largest (meaning, having the most species) of three classes of the Phylum Hemichordata.
Hemichordates have an important place in geologic history. Graptolites, which date back to the Cambrian and are common in Ordvician and Sulirian rocks, are a class of Hemichordata.
If anyone wants to learn more about these animals a good place to start might be these web sites:
